This study, based on the experimental observation of small watershed, uses the GIS platform and the remote sensing data as the distributed hydrological model SWAT. It uses the measured data to simulate the rainfall runoff process in the small watershed of Zi Mu river. The results show that the runoff is more consistent and the model efficiency coefficient is 0.59 after the parameters are determined. The model can better simulate the rainfall runoff process in the study area. Through the determined sensitivity parameters, the sensitivity parameters of the rain season runoff in the study area were identified which will provide reference for the hydrological modeling of the N anxi river state.
